3. Model and Results of Internship in Local Industry

Model of industry internship in local industries was developed in two industries: UPT Logam in Yogyakarta and UD RekayasaWangdi in Sleman. Three groups of student internship took part in this model. They did this internship model for two months in these industries. Then in the nest semester they took Final Project Course for one semester to continue working in the groups to manufacture what they had designed during the internship. In other this internship model is call an integrated internship model, where Final Project Course is initiated during the implementation of industry internship program. The students implemented four-stage: a pre-placement, b initiation, c working, and d termination. They did pre- placement stage by identifying, investigating, interviewing and determining alocal industry as an internship placement site with input from the potential internship supervisor and academic instructor. After a mutual decision is agreed upon, pre- placement activities include setting a work schedule, continuing contact with the future internship supervisor, rearranging personal schedules. In the initiation stage, the studentsdidorientation program for two weeks. They observed process of production andtried to find out the real problems in the industries under supervision.Then, during the working stage, the studentsworkedin groups as regular workers to design and manufacture a machine. The students spent this stage for six weeks. In the termination stage, the students completed the tasks and wrote a report of the internship. Products of the integrated internships model were three machines designed by the internship students. These machine were cutter machine, slondokmolding machine and sifter machine.

3. 1. Cutter Machine

The students who did the internship inUPT Logam Yogyakarta designed a cutter machine Fig. 1.This machine is used in finishing process. Traditionally after the casting process, workers cut the pouring line of casting by using a handsaw. To cut one piece of part, it took for about 10 minutes and very exhausting. The machine is operated manually. In one minute, it can cut 12 pieces. Figure 1. Cutter Machine

3. 2. SlondokMoulding Machine

The students who did the internship inBengkelRekayasaWangdi in Sleman designed a SlondokMolding Machine Fig. 2.Slondok is a traditional food which is made of cassava as main raw material. Traditionally slondokis produced manually, as a results, the shape and dimension of slondokare not uniform. This traditional process is slow in production. Its only can produce 3 kg for one day 8 hours by one operator. The molding machine is operated by using an electrical motor. The operator pourthe raw material into the pouring hole. By using this machine, slondok can be produced in uniform shapeand dimension. This machine can produce 40 kg for one day 8 hours by one operator. 205 Figure 2.SlondokMolding Machine 3. 3. Sifter Machine The second group of students who did the internship in UPT Logam Yogyakarta designed a sifter machine Fig. 3. This machine is used to sort out aluminum waste. Traditionally after the casting process, workers sort out the aluminum waste manually. It takestime and very boring. This manual process is also dangerous, because some chemical materials can harm the hands of workers. The sifter machine is operated by using an electrical motor. The operator pours the waste material into the pouring case. Then a roll crushes the material into small pieces. Below the crusher, there is a sifter moving back and forward. By this way, sandscan go through and are felt down, butthe aluminum materialremains. Because of the slope of the sifter, then the aluminum moves down and it is collected in a bucket.

4. Measure of Design Competency

In this study the design competencies assessed were knowledge of procedures, operational skills, social skills and cognitive skills. Every internship student wrote a report about how he or she manufactured the parts of the machine. Therefore the reports were different between one students and others. To assess the knowledge of procedures, the examiner used the report. To assess the operational and social skills, the examiner observed the students, when they were working in manufacturing the machines. This observation was intended to know how students chose and used the machines and tools, how they applied the procedures, the methods, and the technologies. This observation was also intended to assess every student skills: to listen and speak to others individually,how to cooperate and to work in team. The cognitive skills were measured by using oral examination. This examination was done by presentation of every student based on which parts of the machine they were responsible to manufacture. The students were asked about how they solved problem, designed and managed a project, and how they took decisions. The product performance test was done to assess the quality of the machine. Each group of the internship students presented their machine. Firstly, they explained how to operate the machine, how every parts work and it’s utilities and specification. Then the machine was run to know how well the machine work.
